" MACHINE FOR MOLDING CEMENT BRICKS.

To all whom it may concern: p

' Be it known thatI, GEORGE BROWN, a citizen of the United States, residing at Niles, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Machines for Molding Cement Bricks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertainsto make and use the same. 3

My invention is an'improved machine for simultaneously molding a number of cement bricks or othersimilar articles; and it consists in the construction, combination, and arrangement of devices hereinafter described and claimed". I

In the accompan 'ng'drawings, Figure 1 is a top plan-view of a molding-machine embodying y im rovements, showing the .cover elevated. ig'. 2 is an end elevation of the same, and Fi 3 is a transverse sectional view of the same.

The table or frame 1 of my improved molding-machine is formed with a bed2 to support a removable pallet-board 3. 'On one side of the said bed is a side Wall 4, which is fixed and is provided with a number of vertical slots 5, which are appropriately spaced apart, according to the thickness of the bricks or other articles to be molded in the machine. At the ends of thevsaid fixed side wall and rojecting outwardly therefrom are a pair of bracket-arms 6, the outerends of which are connected by a longitudinal bar 7, having I openings 8 therein, which are appropriately spaced apart. Sliding partition-plates 9 operate in the slots 5 and are'provided at their outer ends with outwardly-extending guide arms 10, which pass through and operate in theopenings 8. Said partition-plates form the side walls .of the mold-spaces in which the bricks, blocks, or other articles are formed and serve to space the molded articles apart,

I as will be readily understood. The said parouter ends-connected Supporting-1e s 12 tition-plates have their together by a bar 11. are here shown for the outer end 0 the bracket-arm 6 and for the bar 7 At a suitable distance below the said bar 7 the frame or tableis provided with bearings 13 for a rock-shaft 14, which is provided with operating-levers 15 at its ends and is also provided with rock-arms 16, which are keyed thereto I Specification of LettersPatent. Application filed May 11I 1905. Renewed March 26,

and are connected to the bar 11, sothat by partly turning said rock-shaft by means of one or both of its levers the rock-arms 16 will be caused to move the partition-plates either inwardly or outwardly.

Opposite the fixed side wall 4 is a hinged wall 17, which is adapted to be turned out wardly to a horizontal position and to be. raised to a vertical position and parallel with the fixed wall. ,The pallet-board lies between. the fixed "and the hinged or pivotedwalls, and the latter may be locked in a vertical position by means of lockbars 18, which are here shown as pivotally connected to the ends of the fixedwall 4 and as providednear their outer ends with lock-notches 19 toengage lock-ears 20, with which the hingedwall' is provide Hingedly connected to the upper side of the hinged wall isa cover'21, which when the hinged wall is in a vertical position is adapted to close onto the fixed Wall, and in connection with the pallet-board said fixed and hinged walls and the partitionplates forma the artiti0n-plates have been moved in-' war ly, so that they arecaused-to extend across the pallet-board and to plurality of mold-cavities when I bear on the. f

upper side therof. The hinged cover 21 has transverse grooves 22 on its under side to engage the upper edges ofthe partition-plates to retain the latter in parallel relation.

In the operation of. my molding-machine after the pallet-board has been placed on the bed, the sition-and locked, and the partition-plates have been moved inwardly to lie across. the

hinged wall turned to a vertical po- 9; pallet-board the cement or othercomposl i tion is placed and tamped in the mold-spaces, i

and the cover is then closed, so as and even or true the upper sides of the moldarms. When the composition has sufficiently set, one or both of the levers 15 is or are operated to partly turn the rock-shaft 14 and cause the partition-plates to be drawn outwardly from between the molded articles, so as to separate them and leave them on the pallet-board. The cover is thenraised and to smoothsition to permit of the ready removal of the palletboard, together with the molded arti-" cles thereon, from the'bed of the machine, the molded articles beingretained on the palletboard until they have sufiiciently hardened. suitable number of pallet-boards may be IOO . the hinged wall lowered to a horizontal po-i.

' wall and adapted employed in connection with each machine, so that the latter may be almost continuously in operation.

From theforegoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

' 1. In a molding-machine, a mold embracing a mold-bed, side and top walls inclosing the same, and partition-plates movable into and out of the mold-chamber and coacting with said walls and mold-bed to form a plurality of mold-spaces, one of the side walls. being hinged to swing outwardly away from and below the level of said mold-bed.

2. A molding-machine comprising a support and a mold embracing side walls, a removable pallet between the side walls, and partition-plates, one of said side walls being movably mounted so as to be lowered below the level of the pallet and the other wall being slotted, said partition-plates being slidable through the slots of the latter wall, across the pallet and toward and from the movable wall.

3. A molding-machine comprising a sup port, a fixed wall, a hinged wall, a pallet resting on said support between said walls, and partition-plates extending through the fixed to be moved inwardly across the pallet or outwardly to uncover the same, said movable partition-plates coacting with the pallet and the said walls to form mold-spaces.

4. A molding-machine comprising a mold embracing side walls, one of which is slotted and the other of which is hinged to swing downwardly and outwardly, a removable pallet between said walls and partition-plates sliding through the slots of the slotted wall, across the pallet and toward and from the hinged wall.

5. A molding-machine comprising a support and a mold comprising a mold-bed, side walls, a hinged top wall, and partition-plates, one of said side walls being movably mounted so as to be lowered below the level of the mold-bed and the other wall being slotted, said partition-plates being slidable through the slots of said latter wall, across the bed and toward and from the movable wall.

6. A molding-machine comprising a mold having a mold-bed, a fixed wall provided with vertical slots at suitable distances apart,

and a movable wall opposite the slotted wall mounted to be lowered below the level of the mold-bed, longitudinally-1novable partitionplates in said slots adapted to be moved inwardly across the bed and to be moved outwardly to clear the bed, guides for said partition-plates and means to simultaneously operate said partition-plates.

7. A molding-machine comprising a mold embracing a mold-bed, side walls, one of which is slotted and the other of which is hinged to swing downwardly and outwardly, artition-plates sliding through the slots of the slotted wall, across the bed and toward. and from the hinged wall, swinging lockingbars adapted to engage the hinged wall to lock the latter in its closed position, and. a hinged top wall.

8. A molding-machine comprising a mold embracing side walls, a mold-bed between said side walls and a hinged top wall, one of said side walls being fixed and the other being movably mounted so as to be lowered below the level of the mold-bed.

9. The herein-described molding-machine com rising the table or frame having the bed, the med vertically-slotted side wall and the projecting bracket-arms, the side wall hinged to the table or frame, the cover, the bar connecting the bracket-arms and having 0 venings coincident with the slots in the ixed side wall, the partitionplates movable in the slots in the fixed side wall and having the guide-arms extending through the openings in the bar, and the pallet-board on the bed, under the partition-plates and removable from the bed.

10.
